Abstract
The utility model relates to a lift tower crane which is suitable the vertical transport of the construction of common buildings and high-rise buildings and can perform leftward and rightward rotary material feeding. The utility model comprises a main frame (2), a base (1), a lifting arm (7), a balance arm (6), vertical lift equipment (9), a stay cord (8), etc., wherein a lift sliding sleeve (3) is installed on the external side of the main frame (2), a rotary rack (5) is installed on the external side of the lift sliding sleeve (3), and the lifting arm (7) and the balance arm (6) are connected to the external side of the rotary rack (5). An electric block (11) is used for pulling and driving the lift sliding sleeve (3) to lift upwards and lower downwards; then, the lifting arm (7), the balance arm (6) and the rotary rack (5) are driven to lift upwards and lower downwards. Driven by the rotary rack (5), the lift sliding sleeve (3), the lifting arm (7) and the balance arm (6) can rotate. The utility model solves the problems that the existing tower crane for building construction can not be lifted upwards and lowered downwards freely, and the operation of installation and dismantlement can not be carried out on the ground; furthermore, the existing tower crane for building construction can be easily affected by storm to overturn and is not safe, etc.
Description
(1) technical field:
But the utility model relates to a kind of common buildings and high-building construction vertical transport construction machine of left rotation and right rotation feeding again that is.
(2) background technology:
Tower crane is used in building operation at present more, and body frame single-column fixed can not free oscilaltion, installing/dismounting inconvenience not only, and be subjected to violent storm to shake to cause easily to topple, very dangerous.
(3) summary of the invention:
The utility model comprises compositions such as body frame (claiming the more piece frame again), base, arm, equilibrium arm, vertical lifting equipment, stay cord.Main invention is that the sliding trap of lifting is installed in the body frame outside.Swivel mount is installed in the sliding trap of lifting outside, and swivel mount connects arm and equilibrium arm.With the electric block pulling, the sliding trap lifting of lifting also drives the lifting of arm, equilibrium arm and swivel mount, is subjected to swivel mount to drive sliding trap, arm and equilibrium arm and rotates.Blast has drawn together, and the sliding trap of lifting can drive arm, equilibrium arm and swivel mount and fall the danger of avoiding the high wind attack to topple.
General tower crane can only be undertaken the construction of skyscraper, and the utility model utilizes the reinforced concrete frame in building as the body frame raised bottom, can undertake the construction of high-rise building and random layer high building.

(5) specific embodiment:
According to the skyscraper drawing, determine to install the base point of elevation tower crane body frame (2).The utility model adopts firm banking firmly not crooked from cast 300# reinforced concrete footing (1).Base (1) gives and has buried anchor bolt, above body frame (2) steadily vertically is installed in, uses instrumental correction.Body frame (2) is made with angle steel, smooth no pimple.Dress body frame (2) four joints are then installed the sliding trap (3) of lifting in body frame (2) outside earlier, and sliding trap (3) is high 7～8 meters.Two on roller is installed on the every limit of sliding trap (3) in sliding trap (3) and body frame (2) contact position, is beneficial to slide up and down.Sliding trap (3) is when lifting stops, and body frame (2) is loaded onto safety card (13) control and glided.Swivel mount (5) connection arm (7) and equilibrium arm (6) are installed in sliding trap (3) outside, respectively draw 2～4 steel cables (8) at arm (7) front end, equilibrium arm (6) end and swivel mount (5) top, at arm (7) amplitude variation trolley (9) is installed down and is claimed crane carriage again.Synchronous two electric blocks of lifting (11) are installed at body frame (2) top, and copper rope one end buckles in sliding trap (3) top, and the lifting of the sliding trap of control (3) is comprising the disconnected alarm immediately of electric block steel rope.Anti-(10) two in the case of falling is installed at body frame (2) top, and anti-case chain one end of falling buckles in sliding trap (3) top, and the other end is enclosed within sprocket wheel and hangs in body frame inside, and the sliding trap of control (3) is not fallen down.Swivel mount (5) rotation is driven by slewing, and the vertical hoisting system adopts stepless time adjustment hoister and device control such as limiting device and overload warning instrument, guarantees lifting safety.This elevation tower crane is not established the driver operation chamber, adopts long-distance remote control to handle.
Undertake the construction of the high-rise building elevation tower crane as shown in Figure 2, it utilizes 60 meters high body frames (2) and two cover bases and utilizes a reinforced concrete frame (12) in building to be the body frame raised bottom, when the high 50 meters left and right sides of framework, filling up one centimeter thick iron plate on the framework Beam, four foundation seat steel Beam and annexes on the frame then, body frame (2) held to clip promptly be raised bottom, body frame under the base (2) is folded down, connect with hydraulic brace and to rise body frame (2), when high again 50 meters of framework according to aforementioned installation raised bottom, the purpose that just can reach continuous rising body frame, the skyscraper that so just can build any floor height so alternately are installed.Especially these facility have at any time and can rise the function that can fall, when the high hundreds of rice in building or when higher, draw together time-out as high wind, and this machine can be fallen at any time, and the danger of avoiding the high wind attack to topple has solved the indeterminable difficult problem of general tower crane.
Claims (2)
1, a kind of elevation tower crane, comprise body frame (2), base (1), arm (7), equilibrium arm (6), vertical lifting equipment (9), stay cord compositions such as (8), it is characterized in that: the smooth no pimple of body frame (2), the sliding trap (3) of lifting is installed in body frame (2) outside, swivel mount (5) is installed in the sliding trap of lifting (3) outside.
2, elevation tower crane according to claim 1 is characterized in that: body frame (2) utilizes the reinforced concrete frame in building (12), uses four steel Beam and annex that body frame (2) is clamped again and constitutes body frame (2) base of continuing rising (1).
