Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, has another name called tower crane, and the building operation raws MAT'L such as the reinforcing bar that is used for slinging, wood are stupefied, cement concrete, steel pipe, tower crane is a kind of requisite equipment on building ground.
Along with the development of Building Trade in China, large-scale building in all parts of the country is built one after another fast, building operation is very high for the dependence of tower crane, along with the increase of tower crane demand, tower crane driver demand also increases thereupon, but because the level of current tower crane driver is very different, low-level tower crane driver relies on merely range estimation judgement to operate tower crane, this operation judges mode not only inefficiency, and hidden trouble can be caused to safe construction, some building constructor is just for the monitor and control facility of complex precise installed by tower crane for this reason, the cost of these monitor and control facilitys is very high, be unfavorable for the saving of building operation cost.
In addition, tower crane of the prior art is time on the shelf, and the weight of mass can cause tower body inclining, and tower body inclining can cause between crossbeam and horizontal rotating disc and produce friction, if things go on like this not only also can reduce output power of motor by wear levels rotating disk, infringement motor.The moment on working arm and equilibrium arm both sides is equal just can reach balance, but the weight weight that in real work, tower crane is sling is all in change at every turn, the position of suspension hook is also in change, and the mass weight on equilibrium arm does not change, position does not also become, and therefore in practical work process, working arm and equilibrium arm reach the chance of state of equilibrium seldom, more or less all can cause certain inclination of tower body, even knockdown, can reduce the service life of tower crane for a long time like this.
Utility model content
The utility model proposes a kind of tower crane, solve in prior art that tower crane construction precision is poor, safety is low, problem that tower crane service life is short.
The technical solution of the utility model is achieved in that
A kind of tower crane, comprising: bracing frame, working arm, equilibrium arm and operator's compartment, the junction of described working arm and described equilibrium arm is rotationally connected by horizontal rotating disc and support frame as described above; Described operator's compartment is fixedly connected with the top of support frame as described above; Described working arm be provided with its bearing fit hang head; Described equilibrium arm is provided with the mass with its bearing fit; Monitor screen is provided with in described operator's compartment; Described top of hanging head is provided with camera; Between described camera with described monitor screen, wireless telecommunications are connected.
As preferably, described mass is by being arranged on the sliding tray of described equilibrium arm bottom and described equilibrium arm sliding block joint.
As preferably, described in hang head by being arranged on the sliding tray of described working arm bottom and described working arm sliding block joint.
As preferably, described camera is screwed with described top of hanging head and is connected.
As preferably, the bottom of support frame as described above is provided with the base be fixedly connected with ground.
Principle of work of the present utility model is as follows:
Be positioned at the camera hanging crown end and catch the image hung below head in real time, tower crane driver is sitting in operator's compartment, sees the image hung below head by monitor screen, and according to image accurately judge next step this how to operate.
When on working arm hang head hang the weight of constant weight at certain position time, can, by mass on slide balance arm to certain position, make the moment of working arm and equilibrium arm keep balance, minimizing working arm or the friction between equilibrium arm and horizontal rotating disc.
In addition, when tower crane is on the shelf, by the adjustment position of mass on equilibrium arm, the moment of working arm and equilibrium arm can be made to keep balance, reduces working arm or the friction between equilibrium arm and horizontal rotating disc to greatest extent.
The beneficial effects of the utility model are:
By arranging camera and arrange monitor screen in operator's compartment hanging crown end, the mode of operation and particular location that tower crane driver can be made to understand in real time hang head, be convenient to tower crane driver and make correct judgement and manipulation, be conducive to safe construction, work efficiency is high.
By mass and equilibrium arm are set to bearing fit, working arm and equilibrium arm hold torque state of equilibrium at any time can be made, reduce the friction between horizontal rotating disc, improve the service life of tower crane.
