Abstract

The invention provides a tower crane apparatus. The tower crane apparatus comprises a crane arm, a balance arm, a hoist, an elevator, a winch, a tower cap, a control chamber, a slide rail, a lifting steel wire, a rotating shaft and a tower crane main body, and the tower crane main body vertically stands on the ground; a heating system is arranged in the control chamber; the crane arm and the balance arm are hinged to the lower surface of the tower cap, and can rotate 360DEG; the heating system comprises a heating device and a heat supply device; the heating device is arranged at the right side of the control chamber, and is a rectangular box provided with a space and an outlet; the heat supply device is arranged at the lower portion of the control chamber and provides hot air for the control chamber; the heating device comprises a magnetron, a power transformer, a furnace chamber, a waveguide, a rotating workbench, a furnace door and a temporal power controller; and a heating resistor wire and a water ejection system are arranged in the heat supply device. The tower crane apparatus improves the construction environment of a worker, reduces the fatigue degree of the worker, makes the body of the worker be healthy, and reduces the incidence of occupational diseases.

Description

A kind of tower crane device

Technical field

The invention relates to a kind of engineering machinery field, particularly relates to a kind of tower crane device.

Background technology

The development of tower crane industry, the development of real estate industry, the demand of tower crane is constantly increasing；The upper load that function is subject to jib stay cord and counter-jib stay cord transmits of tower crane point, and transmit tower body structure by structure member formulas such as convolution pylon, turntable, bearings either directly through turntable；With the length of counter-jib inversely, and between counter-jib length and jib length, there is certain proportion relation in the consumption of balance weight.Counterpoise is considerable, and light-duty tower crane generally at least wants 3～4t, and heavy wants nearly 30t.Control station is absolutely empty at height, it is generally known that on 20m, above wind big, temperature is relatively low, and particularly in cold winter, high-altitude is cold；In order to operate conveniently, safely, the outside mainly clear glass of control station is constituted, and the ability of the cold resisting, operator's construction environment is severe

Summary of the invention

The problem that the invention to solve is to provide a kind of tower crane device.

For solving above-mentioned technical problem, the invention the technical scheme is that a kind of tower crane device, by crane arm, counter-jib, hoist engine, elevator, winch, tower cap, control room, slide rail, lifting steel wire, rotating shaft, body of tower hoist, it is characterized in that, described body of tower hoist be vertically stand in ground；A heating system is had in described control room；Described crane arm and counter-jib are hinged on below tower cap, it is possible to do 360 degree of convolutions.

Further, described heating system includes heater, heating plant.

Further, described heater, on the right side of control room, has space to have the rectangular cases of outlet.

Further, described heating plant, in control room bottom, provides hot-air for control room.

Further, described heater includes magnetron, mains transformer, furnace chamber, waveguide, rotary table, fire door, temporal power controller.

Further, there are a resistive heater and a water injection system in heating plant.

Further, described water injection system includes water storage device, Shower tap.

The invention has the advantage that and has the benefit effect that the working environment improving staff, allows and also can have well very warm working environment in cold winter, improves the work quality of staff, reduce the probability of the generation of accident to a certain extent；Staff is prevented to freeze numb and the probability of generation accident at cold extremity in winter.

Detailed description of the invention

A kind of tower crane device, by crane arm, counter-jib, hoist engine, elevator, winch, tower cap, control room, slide rail, lifting steel wire, rotating shaft, body of tower hoist, it is characterised in that described body of tower hoist be vertically stand in ground；A heating system is had in described control room；Described crane arm and counter-jib are hinged on below tower cap, it is possible to do 360 degree of convolutions；Described heating system includes heater, heating plant；Described heater, on the right side of control room, has space to have the rectangular cases of outlet；Described heating plant, in control room bottom, provides hot-air for control room；Described heater includes magnetron, mains transformer, furnace chamber, waveguide, rotary table, fire door, temporal power controller；A resistive heater and a water injection system is had in heating plant；Described water injection system includes water storage device, Shower tap.

Control room is in the main body of tower crane, aerial at height, is terribly cold in cold winter, has had heating system passable, solves operator when work high above the ground, and extremity freeze to obtain numb solution potential safety hazard；While heating, also can lose substantial amounts of moisture, make air drying, allow operator not feel well；In order to alleviate this situation, add water injection system, spray a small amount of water, allow air humidity increase；Reduce the uncomfortable sensation reduced owing to moisture increases；

Heating system also has a heater；Tower crane is in high-altitude, not very convenient up and down, in the process repeatedly climbed, is also danger close；In order to reduce danger incidence rate, reduce operator physical demands, operator can band working lunch, for working lunch heat, solve food problem in the air at height.In order to meet work, it is provided that the better mental status.
