Abstract
The utility model relates to a high-speed tower crane which mainly comprises a tower body, two front arms, a rear arm, trolleys, a cab and a tower cap, wherein the two front arms are arranged on the tower body; the rear arm is arranged on the tower body, is placed on the same horizontal plane on which the two front arms are positioned and forms an angle of 180 degrees with the center line of an included angle of the two front arms; the cab is arranged on the tower body in the included angle between the two front arms; the tower cab is arranged at the upper end of the tower body; the trolleys run on the front arms. Due to the design, the high-speed tower crane disclosed by the utility model avoids front-and-back swinging of a heavy object during rotation of the front arms by virtue of the stability of a triangle and improves the steadiness and the safety in the work. The two trolleys jointly lift the heavy object, so that the lifting speed and the bearing capacity are increased; due to the stability of a triangular structure, the front arms can be quickly rotated to required positions, and the working efficiency is improved.
Description
Technical field
The utility model relates to special equipment field, concrete relates to a kind of high speed tower crane.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, with a section spreading (height), as the form of a steel tower, is also tower crane, is used for hanging the raw-material equipment of constructing such as working reinforcing bar, wood are stupefied, scaffold tubes.A kind of requisite equipment of building operation.Particularly in recent years, development along with national economy, real estate industry has obtained unprecedented growth, and being subject to people as the very important instrument of real estate industry, tower crane more and more payes attention to, tower crane technology is development rapidly also, various new-type tower cranes constantly occur, characteristic and performance is also more advanced.
Yet, so far, comprising that various new old-fashioned tower cranes are all single forearms, vertical lifting weight, rotates forearm after slinging and weight is moved to want the position of placing.Lifting rope (steel rope) is that due to the inertia of weight, in fast rotational forearm, weight relatively forearm swings backwards vertically down.And when forearm cut rotates, due to motional inertia, weight will move forward, form swing forwards.So, caused hoisting crane forearm stressed unstable, swung to and fro, so that the generation of Peril Incident.For the sake of security, the rotative speed while having to reduce tower crane handling weight, has so just reduced work efficiency, does not meet era step rapidly and efficiently.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high speed tower crane.
In order to realize above-mentioned target, the utility model is taked following technical scheme:
A tower crane, mainly comprises tower body, forearm, postbrachium, dolly, operator's compartment and tower cap, and described forearm is divided into two, is arranged on tower body; Described postbrachium is arranged on tower body, in same level, becomes 180 ° with the line of centers of two forearm angles with two forearms; Described operator's compartment is arranged on the tower body between two forearm angles; Described tower cap is arranged on tower body upper end; Described trolley travelling is on forearm.
Described two forearm angles become 30 °, between two forearms, have crossbeam, and crossbeam is fixedly connected with two forearms, and two forearms and crossbeam are A font.
Described dolly has two, operates in respectively on two forearms.
The utility model beneficial effect is embodied in:
1, steel rope and crossbeam form triangle, utilize leg-of-mutton stability, and weight swing while having avoided rotation forearm, has improved the stationarity of operation.
2, during handling weight, can twirl forearm, to the position needing, improved work efficiency.
3, improved the safety of operation.
Accompanying drawing explanation
Fig. 1: high speed tower crane schematic diagram;
Fig. 2: the geometric relationship figure of crossbeam, steel rope and weight;
In figure: 1, suspension hook, 2, steel rope, 3, crossbeam, 4, dolly, 5, forearm, 6, tower cap, 7, postbrachium, 8, operator's compartment, 9, tower body, 10, weight.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
embodiment:a tower crane, mainly comprises tower body 9, forearm 5, postbrachium 7, dolly 4, operator's compartment 8 and tower cap 6, and described forearm 5 is divided into two, is arranged on tower body 9; Described postbrachium 7 is arranged on tower body 9, in same level, becomes 180 ° with the line of centers of two forearm 5 angles with two forearms 5; Described operator's compartment 8 is arranged on the tower body between two forearm angles; Described tower cap 6 is arranged on tower body upper end; Described trolley travelling is on forearm.Described two forearm angles become 30 °, between two forearms, have crossbeam, and crossbeam is fixedly connected with two forearms, and two forearms and crossbeam are A font.Described dolly has two, operates in respectively on two forearms.
During handling weight, the chaufeur in operator's compartment 8 is controlled two dolly 4 advanced in unison, puts down suspension hook 1.After hanging up weight 10, be promoted to the height needing, then fast rotational forearm 5, to the position of needs, is fallen weight 10.Whole process is convenient succinct as operation ordinary bridge crane, and because crossbeam 3 and the formed triangle of steel rope 2 have stability, so can rotate rapidly forearm 5 when slinging weight, can not make weight 10 swings because of rotating too fast, improve the stability of transfer velocity and whole tower type crane structure.Because have the common lifting heavy 10 of two dollies 4, accelerated hoisting speed and load-carrying capacity.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
